- Original factory precision ensures accurate temperature control, preventing cold start difficulties and white smoke caused by insufficient preheating.
- A high-frequency consumable part for Sany's 30-ton excavators, with large stock and widespread circulation in the repair market.
3. Procurement and Maintenance Notes
- When purchasing, verify Sany material code 60311918 and OEM number 894390-7776 to ensure compatibility with 6HK1 engine models.
- Replacement Recommendation: It is advisable to replace all 6 preheater plugs as a set to avoid uneven starting performance due to differences between new and old parts.
- Installation Note: Tighten strictly according to the specified torque (typically 15-20 N·m) to prevent thread slippage or damage.
- Fault Diagnosis: Difficulties in cold starting, white smoke emission, or a constantly lit preheater indicator light are likely indicative of a faulty preheater plug; resistance testing with a multimeter is recommended.
